Fig. 2. Visualization of LSD components.

a, Surface mesh of a segmented neuron from FIB-SEM data (FIB-25⁸ dataset). Scale bar, 1 μm. b, RGB mapping of LSD components 3, 4 and 5. Neural processes are colored with respect to the directions they travel. Intermediate directions are mapped accordingly (see |Cartesian coordinate inset). c, LSD predictions in corresponding two-dimensional slices to the three boxes shown in a,b; neuron highlighted in white. Columns signify neuron orientation (blue, lateral movement; green, vertical movement; red, through-plane movement). Rows correspond to components of the LSDs. First row, mean offset; second and third rows, covariance of coordinates (LSD[3:6] for the diagonal entries, LSD[6:9] for the off-diagonals), second row shows mapping seen in b; last row, size (number of voxels inside intersected Gaussian). Scale bar, 250 nm.
